Yo Unregistered: Join us for the April 1 meeting when it will be Recovery night. We will have demonstrations working with winching, recovery and spotting. We will meet at 7:30 p.m. at Jefferson County Fairgrounds (not Stevinson Toyota but nearby).

I got the card in the mail that my 1995 FJZ80 requires an emissions test. It is currently equipped with 35" tires so every one on the forum knows I am forced to "borrow" tires in order for the state to accurately test my vehicle on the dyno (I/M240).

Politics aside, I have some 16" wagon wheels on the '65 FJ45lpb and need to know how safe it will be to bolt those to my '95 using my 80's lugnuts. I DO NOT want to end up in the ditch in a ball. The E-test center is a mile from my house so all I need is it to make it there, run their POS test, and make it home.

Thank you in advance...I wish there were reasonable accommodations to test my vehicle safely but here we are...

Q.
Wheel Sizes and Dynamometers?
A.
Front wheel and all wheel drive vehicles with low profile rim sizes 17 inches or larger in diameter, or vehicles with wheel sizes larger than 34 inches cannot be safely tested on the dynamometer.

Only vehicles with manufacturer-equipped undersized or oversized tires that do not fit safely on the dynamometer will be authorized by the state to undergo an idle test instead of a dynamometer test. Vehicles with tires larger or smaller than original equipment that do not fit safely on the dynamometer must be returned to stock condition for testing. Vehicles with non-original undersized or oversized tires will not receive authorization from the state for an idle test.

Because of OEM design and/or safety considerations, some 1982 and newer vehicles are not tested on the dynamometer, but are instead tested with the Two-Speed Idle Test. These include but are not limited to:

Let's say you own a Toyota RAV4! you read that correctly, it cannot be tested on the dyno and the state will allow a two speed idle test.... what's that?! the two speed idle test doesn't test NOx. Awesome....

The two-speed idle test is performed on 1981 and older gasoline-powered passenger cars and light duty trucks, and on 1982 and newer gasoline-powered, heavy duty vehicles with a gross vehicle weight (GVW) greater than 8,500 lbs. The idle test uses a tachometer and a probe to monitor idle emissions. This test analyzes the carbon monoxide and hydrocarbon emissions, but not oxides of nitrogen (NOx). There is no driving simulation.

I would be wary of that swap with the presumption that your 80 uses the shank-style lugs, and your 45 rims likely has the conical style? Those shankers would bottom out before they held the rim tight to anything. Is there a reason you can't also use the 45's nuts?

The stock 95-97 80 series lug nuts for the hub centric wheel have a taper to allow the use of steel wheels in an temporary time period. So, for your situation Mike I would think you would be OK. It is done this way as spares in some situations are steel. As for if the your cruiser will tip over with the use of small tires, that will be any one's guess.

Another thing to consider is that most 80 series sold in 3rd world countries had steel wheels with the conical lug seats and conical lugs. You should be fine.

When I last did my Tacoma (2007 TRD) they did the tailpipe test. I asked why and they told me that the traction control wouldn't work on the treadmill. I told them you can disengage it and they said that it would automatically reengage over a certain speed. I am pretty sure they're full of it and they still charged me the full treadmill test price. I hate emissions testing with a passion.

went for a 180 mile road trip that ended at the testing station
I like the Fredrick station - exit 235 off I-25 and one light from highway off ramp

unplugged the batteries for a day prior to the test
this fixed my high idle issue - was at 1200, dropped to 650 or so

O/D off

heater on hot - fans off
ran the rear heater to circulate coolant

windows and sunroof open
this allows the driver to hear the engine/tires and appears to result in a smoother test with less WOT/rapid decelleration

headlights and all electrical accessories off

3/4 full tank of 91 octane
shell if that matters

wore respectable clothes
it works

cleaned the truck and interior
If I care about the car, perhaps they will care about the test

newer cap, rotor, plugs, plug wires

new exhaust with two new cats

three bottles of HEET in the tank
red not yellow - Isopropyl alcohol

over inflated the tires to 65psi

2ND start off

PWR off

waited for cool day - ambient temperature 59 degrees

Swapped the tires from 35x12.5x17 to LT235/86R16 (31s?)
I weighed them for fun -
35Toyo/Hutch = 135lbs
e-tires and rims = 74lbs

Got pulled over in Ft.Collins for not having a front license plate and driving a truck in pieces. He wanted to make sure I didn't steal it.

Idle back to 650 after resetting the computer

First test no CEL - second trip through (4th pass) P401 came on. They did change the law so a CEL isn't an automatic failure. I had to run the test 4 times because the first passed the sniffer but, they failed me for not having two catalytic converters. The gal there was really nice and she crawled under the truck and verified the two bumps were in fact two cats.

PASSED!!!!!!!!!!

Interesting how that whole "grams per mile" thing was never a requirement or parameter when our rigs were design, built and certified. But now the lawmakers of state of Colorado, have decided to usurp the original federal rules and standards that the automakers designed, built and sold their vehicles to and will instead impose new state rules with no regard to their constituents. This is kinda like the people's republik of kalifornia and their CARB.
